Varenicline: Mounting evidence supports lack of neuropsychiatric effects



The use of varenicline (Chantix—Pfizer) for smoking cessation did not increase the risk of neuropsychiatric events including depression, suicidal ideation, and aggression, according to a recent large analysis. The rate of neuropsychiatric events in patients taking varenicline was lower than in patients using nicotine replacement therapy.
